needs to rethinking:

I guess minimally we want to only add x grids to the plot if that flavour gets used in that particular dataset. Then if we're doing that I guess we want to do something with the rug plot heights based on the weighting of that particular x point.
Don't think I can add much to this before meeting tomorrow and it's basically useless right now (If I didn't tell you there was a rugplot you would probably think I'd just put a single black stripe at the bottom of each plot).
